HORACE WALTER DOVER, OF NORTHAMPTON, ENGLAND.

EAN13-WHEEL.

To all whom t may concern:

Be it. Iknown that I, HORACE WALTER DOVER, a subject of the King of Great Britain, and resident of Holyrood, St. James End, Northampton, in the county of Northampton, England, have invented certain new and useful Improvements in or Relating to Hand-Wheels, of which the following is a specification.

This inventionwhich relates`r to hand wheels, such for instance as are employed for steering motor vehicles, for the operation of sto'p cocks, controlling aircraft, motor boats, gun mechanism, and for other purposes, constitutes a modification of the invention described and claimed in the specication of my prior ,Letters Patent No. 1,294,885.

In the preferred forni ofthe invention described and illustrated in the specification of my said prior Letters Patent each of the two halves of the wheel is formed with a half nave and the complete nave portion, resulting from the superposition of the one half upon the other, is securedto a flange' on a hub by means of rivets the top and bottom of said hub passing through circular apertures atV the centers of the two halves. Inasmuch as the size of the steeringpillar or other spindle on to which the hand wheel is to be fitted may vary considerably. and inasmuch as the method of lattachment of the hand wheel to such steering pillar or other spindle may also` be subject to many variations'it follows that thefhand wheel as a whole, which includes the hub,v can only be completed when the design and size of the hub are known.

The object of the present invention .is to provide an improved construction of handwheel of this kind capable of being produced asa whole, irrespective of the size of' or nave portions of the wheel and has sccured Ythereto bolts or like means of attachment which pass through aperturesin an project below the lower half, whereby the complete` wheel may be secured to a steering pillar orr other spindle or to a hub or the like.

Specification of Letters Patent.

Application filed July 16, 1919. Serial No. 311,159.

The lower half of the wheel may also be formed of stampedyor pressed sheet 'metal which extends over or across. the central or nave portion of the wheel or the lower half of the rim, the lower part of each spoke,

The invention is illustrated by the accom-V .panying drawings wherein Figure 1 is a side view and Fig. 2 a part plan view-of one form of the improved wheel, while Fig. 3 is a section on the line 3-3 of Fig. 2. Those parts 0f Figs. 1 and 2 which are to the right of the centerline are shown in elevation and plan-respectively, while those parts to the left of the same line are shown either wholly or partly in section.

Figs. 4 and 5 are similar views to Figs. 1 and 2, but showinga modification of the invention, while Figs. 6 and 7 are cross sections on the lines 6 6 and 7 7, respectively, of Fig. t.`

Referring particularly to Figs. 1 to 3 a,

. is a stampingP constituting the upper half of the wheel, and is formed with an annular rim-portion Z), a plurality of `half-spokes c, and a half nave ai whichextends completely over` or across the central portion of the wheel as at "6. f is a stamping constituting the lower half of the wheel, and is formed with portions g, h, y' and k corresponding respectively with the portions b, c, d and e of the stamping a, so that the two ustampings, when superposed the one upon the other, together form a wheel whereof both the rim and the spokes are elliptical in 'cross section.

At their inner ends, the upper and lower halves c and 71. of thefspokes merge into the upper and lower halves d and j of the nave of the wheel and at their` outer ends they merge into the upper and lower halves b and g of the rim.

rFhe central portion e is pierced and pressed in as at m for the passage therethrough of the elongated square heads n of the' bolts o the central portion 7c being correspondingly pierced for the passage therethrough of the Shanks of said bolts. The heads n of the bolts o are of such length in vthe direction o'f their axes that when the shoulder at the junctionv of the head and shanl of a bolt rests upon the upper side of the central portion if, the top of said head will be substantially flush with the upper side of the central portion e.

After the two halves of the wheel and the bolts o are assembled the whole, with `trial such as Celluloid, exonite, or similar material or a non-inflammable material capable of being molded in a similar manner.

If desired, themarginal parts of the rim and spoke portions in the two stampings ymay be inturned so as to seat the one upon the other and strengthen the structure; the

marginal parts of the rim portion being shown as inturned at g in Fig. 1, whereas in y Figs. 1 and 3, the spoke portions of the two stampings are' shown as butt against the other at r. i v

The outer ends of the spoke portions c and 7L may be united by rivets t passing through apertured distance pieces u Preferably thedistance pieces u are jointed one vcountersunk and the portions c and h are apertured to give passage to the shank portions of the rivets t so. that when the rivets are-closed the margins of the portions c and h around `the rivet holes are drawn into the countersunk holes in the distance pieces u. as at c, Fig. 1 and the heads of the rivets are flush with the surfaces of the portions c and 7L.

The modified construction shown in Figs. 4L to7 is substantially the same as that illustrated in Figs. 1 to 3, likereference letters indicating like parts in both forms of the .i'nvention.` The principal difference lies 'in the means for securing the portions of the wheels together atthe nave;. it is to be observed however that the marginal parts of the rim portion are more inturned at g than in the form of the invention shown in Figs. 1 to 3, while the lower spoke portion L changes from semi-elliptical to substantially V cross section as the nave of the wheel is approached.

the lugs y/ end andA in .thelassenbling of the parts the conforming with the configuration of the central portion q. Each of the apertures in 1s countersunk at its upper head of each bolt w is riveted over and presses the margin of the aperture in the upper portion of the wheel into the countersunk hole as at e, the rivet head being made flushwith the surface of said portion.

. In some cases and in either form of the invention the upper and lower portions of the rim, or those of both the rim and the spokes, may be secured together by first wrapping themgspirally with a tape -11 of linen 'or other fabric, after which t-he moldable material may be applied as above mentioned. f y

The 'underside of the rim portion of the casing of the wheel may be formed, when molded, with a plurality of ribs A12 leaving indentations or finger gaps to facilitate the gripping of the wheel by the user, but I make no claim to this feature.

The bolts 0 or w serve for attachment. of the complete wheel to the end of a spindle, such as a steering pillar 13 shown in dot andv dash lines in Fig. L1, in caseswhere a flange is provided, such as is indicated at 14 or to a hub fitting such as is indicated a't 15A in dot and dash lines in Fig. 1 provided with such a iiange, in cases where it is desired that a hub shall be employed. It will be seen, therefore, that the improved hand wheel is capable of being produced as a whole, irrespective of the size of the steering' pillar or other spindle towhich it is to be fitted and irrespective of the type of hub fitting which may be required.

In a two-part hand-wheel, a stamped rim, spoke and nave upper half; a rim spoke and nave lower half; the nave portion of said upper half extending completely over portions of said halves extending completely across the central portion of the wheel; bolts secured to the nave portion of -said upper half; the nave portion of said lower half being formed with apertures through which said bolts pass and pro-ject below said lower half; and a casing of molda-ble material around said upper and lower halves.
